2: Characteristics and technical parameters of each component
1. Extrusion system
characteristic:
(1) The extruder requires high production efficiency, good plasticizing quality, uniform color mixing, and uniform color of the produced hollow products. The internal and external quality of the products can meet the inspection requirements.
(2) Suitable for processing mixtures of powders, granules, recycled materials, and colorants.
(3) Wide adaptability to raw materials.
(4) The proportion range of recycled materials added is wide.
technical parameter
(1) Screw diameter: outer 100/inner 110mm.
(2) Length to diameter ratio: 30:1. Equipped with ZLYJ280/315 gearbox
(3) Screw material: High quality nitride steel is selected, with surface nitriding treatment, nitride layer thickness of 0.4mm, and hardness HV ≥ 900.
(4) Material barrel: High quality nitriding steel 38CrMoAIA is selected, with the inner surface treated with nitriding and a hardness of HV ≥ 900.
(5) Drive mode: AC motor is selected, variable frequency automatic speed regulation is used to ensure that the twisting material does not stop during normal production. The motor is connected to the gearbox belt.
(6) Drive power: 75/90KW
(7) Screw speed: 0-55r/min Low speed high-efficiency screw.
(8) Temperature control: Adopting the Italian Jeffren automatic temperature control module, it can achieve PID precision control
